Have three plants in rock wool under a 1000 w Hps light and just currently turned to veg from seedlings, just want to know how often i should be watering? I have a top feed system that drains then recirculates. Thanks very much
once a day, maybe once every two days...you can probably hand feed for the next few weeks. My plant are 4 weeks old, the get watered basically every other day by hand. I go by the weight of the pot, when it feels light, water it.
